Re:File Restoration/Recovery

Now, you could put the tablespaces in read only mode, then the copy
would work. But then again, could you put all the tablespaces in read
only mode ?

hmmmm, don't think so :).

Gary,

Only if 1) The database is shutdown prior to the copy of the
datafiles, and
everything else that compromises the database (online redo, control
files,
etc...) or 2) the effected tablespaces are put into hot backup mode
before the
copy, in which case when you restore the files Oracle will ask for the
archive
redo to roll them forward to the rest of the database. As far as
"returning the
skeleton database based on these files" he's smoking something good!!
What I
believe he's more likely asking for is a schema export.

A developer working on a Solaris 2.6 server running Oracle 7.3.4 desires
a nightly backup (by simply copying them to a backup directory) of the
datafiles of an active instance. I explain that it will be a waste of
tape because the files will be corrupt and useless. He counters, "As
long as these files are there, irrespective of their state, oracle [sic]
provides the tools to restore the skeleton database based on these
files."

Will this be the case? I understand that there will [most likely] be
some loss of data, but will Oracle "fix" itself to a point where it's
useful again? TIA
